Just saying, having the revodrive will absolutely maul any system that does not have one. You could upgrade it to a 480gb revodrive if you wish, however that would push it over $5000, so maybe if you get 2 7970's and a 480gb revodrive. This would work. Either way it will be extremely fast.

Heh. I think that just might bring the total build price a little ((><) space between the angle brackets) outside the budget. However, I will investigate the Revo drive. At first glance, I have to say I am impressed. I'll post an update to the build later.
